简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 N0]C?+ BKd03s= 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: {KH!PAh enableservice('AutomationServer', true) dfo_R enableservice('AutomationServer') s&>U-7fx" eSAB :L,K 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 /UwB6s( l1<]pdLTR 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: mmN!=mf* 1. 在FRED脚本编辑界面找到参考.
